• Inhalation Risk: A nuisance-causing concentration of airborne particles can be reached quickly when dispersed.
• Effects of Short Term Exposure: May cause mechanical irritation.
• Uses: As non-toxic stabilizers and lubricants, mold release agents of polyvinyl chloride and water repellent of textiles. As lubricant of coating paper and paint. As internal lubricant and non-toxic stabilizers of polyvinyl chloride, and as mold release agents of the foundry industry. Anti-caking agent; adhesive; emulsifier; lubricants; mold release agents; stabilizers; thickeners; flavoring agents. As stabilizers and lubricants of polyvinyl chloride, and as non-toxic food packaging, medical devices and other soft film containers. As halogen absorbent of polyethylene and polypropylene, it can eliminate residual catalyst in resin. As lubricant of resin colors and molding products, but also as release agents of phenolic, amino thermosetting plastic and plastics and lubricant of polyester reinforced plastic, as thickening agent of grease, waterproofing agents of textile and flatting agent of paint. Food grade Calcium stearate can serve as an anti-caking agent to prevent powdered or crystalline food from aggregation and agglomeration, keeping free-flowing. But China's GB2760-86 allowing the use of anti-caking agent is currently only potassium ferrocyanide which is used for salt. According to the FAO/WHO regulations, Calcium stearate can be used for coating glucose powder, sucrose powder and stock cube, etc. , the maximum allowable amount is15 g/kg. As a waterproofing agent, lubricant and plastic additives. It is widely used in food, medicine, cosmetics, plastics and rubber industries, mainly used for lubricants, emulsifiers, stabilizers, release agents, accelerators, cosmetic base materials. In the rigid plastics, it can increase the speed of the condensate. It can also be used for food packaging, medical devices and other non-toxic flexible film, but also has the effect of stabilizing agent and good long-term stability. As stabilizers and lubricants of polyethylene and polyvinyl chloride. As halogen absorbent of polyethylene and polypropylene, it can eliminate the adverse effects of residual resin on catalyst resin color and stability. It widely used to improve the heat resistance of plastic in foreign countries, improving weather resistance initial color and breathability. It will replace the toxic stabilizers with same performance. For waterproofing fabrics, cement, stucco, explosives; as a releasing agent for plastic molding powders; as a stabilizer for polyvinyl chloride resins; lubricant; in pencils and wax crayons. Food grade calcium stearate, derived from edible tallow, is used as a conditioning agent in certain food and pharmaceutical products. Calcium Stearate is the calcium salt of stearic acid which functions as an anticaking agent, binder, and emulsifier. it is used in garlic salt, dry molasses, vanilla and vanilla-vanillin powder, salad dressing mix, and meat tenderizer. it can be used for mold release in the tableting of pressed candies. Calcium Stearate is a salt of Stearic Acid used in the synthesis of surfactants and detergents due to the fatty acid component of its structure.
• Description: Calcium stearate is carboxylate of calcium that is found in some lubricants and surfactants. It is a white waxy powder.
